Santa Invasion mod for Half-Life 2

Lonely dark night. The people of the city, Ekkir, are going peacefully down the streets. Without any worries, and enjoying the main street, something happens. The city sirenes turns on, the citizens is told to stay indoors. What is happening!? Children running home from their playgrounds. All shops is being closed. In only 2 minutes, the whole main street was empty. In only 2 minutes. The whole city was under attack! Ekkir was told, that some weird UFO (Un-identified Flying Object) was flying over the city. They said it looked like a sleigh. And they were dropping boxes in different colors, towards the city, on all city chimneys. Now it was time to call the military force of Ekkir, to take care of these invaders. What they didn't know, was that this was Santa Claus. As Ekkir isn't in contact with the rest of the world, then Ekkir don't know, what all others around the globe does. Santa couldn't understand this, why was the city forces called to duty? But without time to ask the question, he wouldn't stand back and see his Elf's getting killed. It was time to strike back! Santa got literally pissed. As santa was putting up his outpost outside the city, looking just like Santa's workshop. Military forces was putting up their defences inside the city walls. As the military officers are sending out their jeeps and recruits to blow up santa's outpost. Santa is sending out his elf's and sleighs to take out, and blow the military defence post. Who will win the epic battle?
